Public ISBD Titre : Diversité biologique dans les Triticum et Hordeum : possibilités de création d’une nouvelle variabilité génétique. Type de document : texte imprimé Auteurs : Chafia Zerafa, Auteur ; M Benlaribi, Directeur de thèse Editeur : جامعة الإخوة منتوري قسنطينة Année de publication : 2017 Importance : 182 f. Format : 30 cm. Note générale : 2 copies imprimées disponibles Langues : Français (fre) Catégories : Français - Anglais Biologie Tags : Biological diversity  Triticum  Hordeum  UPOV  Genetic resource  variability Index. décimale : 570 Sciences de la vie. Biologie Résumé : The aim of this study is to characterize and first express the biological diversity of a number of the genotypes of the Triticum and Hordeum genus in order to know the basic traits that can be exploited in the improvement of these cereals. In this context 10 cultivars of hard wheat Triticum durum Desf., 6 of wheat Triticum aestivum L. and 6 others of barley Hordeum vulgare L. have been experimented for several successive years. The cultivation is carried out in pots on agricultural soil and the tests are carried out in the glasshouse of the biopole at Mentouri University under semi-controlled conditions. Thus, a number of characteristics related to the vegetative apparatus, the reproductive system and the grain are monitored throughout the life cycle of the plant that is to say from seeding to Maturation of the caryopses. In addition to the phenological aspects adopted by UPOV in the framework of the DSH and expressed by the Soltner (1982 and 2005) model, the characterization concerned, in order to determine relative precisely the duration of expression of each development phase, some adaptation traits A cross-breeding trial between varieties of each species is then taken in the second step with the aim of creating variability. The findings suggest a great intra and inter-specific biological diversity represented particularly by certain basic characteristics such as precocity glaucescence and others relative to the production. They also reveal a wide variability in the heritage of available cereal genetic resources that can be easily exploited in the creation of a new variety in wheat and barley. This is demonstrated through our trial or hybrids are obtained by the approach pollinating method.

To do this, we started by characterizing the parental genotypes of the three species under study (T.durum Desf., T.aestivum L., H.vulgare L.) and by evaluating the morphophenological and physiological characters through the creation of descriptive sheets according to the recommendations of the U.P.O.V to know the amount of the genetic variability in order to choose the appropriate methods before to launch in improvement programs. The experiment was carried out in a glass greenhouse at the Bio-pôle of the Laboratory for the Development and Valorization of Plant Genetic Resources in Chaâb Erassas, University of the Mentouri brothers Constantine 1, for five seasons. The results obtained and related to the parents showed a significant difference between the genotypes of each species through the phenology, the descriptive sheets and the characters of production and adaptation. These results suggest that hybrids from these parents will be highly different from each other. Once this step is performed, A half-diallel crosses are undertaken between the parents judged to be better for creating a new variability and of proceed for the comparison the genetic potential of four (4) durum wheat cultivars, four (4) bread wheat and five (5) barley with their F1 hybrids as well as, the hybrid of second generation (F2) for durum wheat. The parental genotypes and their hybrids are then sown in a complete randomized blocks design with three repetitions in half-diallel following method 2 and Model 1 of Griffing (1956). The results of the first generation of each species indicated the importance of the additive and non-additive effects in the inheritance of traits under study with the preponderance of additive gene effects for the spike length with beards, the length of beard and the number of nodes per plant. The two effects of additive and nonadditive genes are equal to the of spike length in barley. The effects of additive genes were observed in heredity of the neck spike length, plant height, spike length with barbs, the length of beard, the number of spikelets per spike, the fertility of the spike and the number of grains per spike at common wheat, while controlling flag leaf area, spike length in the first generation of durum wheat and the number of nodes per plant in the second generation (F2). Non-additive gene effects were recorded for the rest of the traits studied. The parents Rihane 03 and Akhrash of barley, TSI \ VEE and Florence aurore of bread wheat and Djeneh - Khataifa, Guemgoum Rekham in durum wheat have recorded in F1the best significant values for general combining ability (GCA) for some characters of production and adaptation. The same observation was noted in F2 for the same genotypes of durum wheat. It is therefore suggested to use these parents in cereal breeding programs because of their ability to inherit these traits from to their descendants. Several hybrids record positive values of specific combining ability (SCA) due to additive X additive genetic interaction and present the highest values of heterosis in F1. These are the hybrids Akhrash x Beecher10, Jaidor x Akhrash in the barley, TSI \ VEE X Mexipak in bread wheat and Djeneh-Khetaifa x Guemgoum Rekham in durum wheat. The value of heterosis decreases certainly in F2, but remains in favor of the hybrid Djeneh –Khetaifa x Guemgoum Rekham. While the F2 generation of hybrids Béliouni x Guemgoum Rekham and Béliouni X Djeneh –Khetaifa are distinguished by the highest positive values of specific combining ability and a important heterosis effects. These hybrids can be adopted as new genotypes inheriting the traits of production and adaptation, hence the interest of continuing their selection in isolated generations to reach pure lines cultivated in fixed varieties. The study of heritability in the narrow sense showed strong values in half of the characters studied for barley and in thirteen (13) traits of common wheat and four (4) traits for durum wheat in the first generation and one trait for the second generation, while, heritability values in the broad sense are high for most traits studied in the three species.

The experiment was carried out in a glass greenhouse at the Bio-Pôle of the laboratory for Development and Valorisation of plant Genetic Resources in Chaâb Erassas, University of the Mentouri Brothers Constantine 1, for six seasons. The morphological study was carried out in order to study the tillering morphology, and the anatomical study that led to the laboratory at the level of the tillering beds during the 1st phase of the growth in order to follow the formation of the buds of the tillers, through which we selected varieties with high BT potential formed. and then on hard grains (swollen) and grains hardening at the end of the cycle (maturing grain), using the manual method (with a razor blade) and the automatic method (microtome) and stained with Carmino green. The results of the morphological study showed that early tillering from the 4th leaf outlet in all varieties, the number of tillers varies from one species to another, these tillers (branches) can become ears but they are less numerous than the number of vegetative tillers. the anatomical study on the tillering tray (corn), observations of histological sections under Laica photonic microscope and carmin green showed a variation in species and in genera, their number increases in stage L1(one leaf) until L4 (for leaf), then (T1) (one tiller). At stage (T1), Rihane is the largest in number of BT formed, Jaidor being the lowest in this phase compared to other varieties. In (4L), M.Demias formed four tiller buds (4BT) while Faurore was the weakest formed (2BT). In stage (3L), Haurani, Jaidor and Saida 183 formed two buds (2BT), while the other varieties formed one bud (1BT). For stage (2L), Beliouni, M.Demias, Mexipak and Rihane formed two buds (2BT), the two variéties Hedba 3 and Jaidor formed a bud (1BT), while the other varieties Beliouni, F.aurore and Saida 183 did not produce of bud. In stage (1L), both Jaidor and Hedba 3 were observed to be early bud formation with (1BT), whereas Beliouni, F.aurore, M.Demias, Mexipak and Rihane did not have buds. The results of the anatomical study of the durum grain showed that no BT was observed during grain imbibition, while the area below the top was colored pink, indicating that it was primary axillary meristems AXMs. The study showed that durum wheat and barley in the half hard stage had two buds, the coleoptile BC bud and the bud tiller BT at the axil of the first leaf, while in the wheat bread, we could distinguish a bud BC. As far as the cross sections are concerned, we have been able to distinguish the Meristem masses beneath the summit, which shows that Meristems can later differentiate to give BT buds then Tillers. We concluded that AXMs are formed at the embryonic stage and begin to be alerted during germination. Note de contenu : الملاحق.
